Lightning Impulse Breakdown Characteristics of Frozen Soil

IEEE Transactions on Power Delivery, 2008
The impulse characteristics of frozen soil are the fundament for the lightning protection design of the overhead transmission lines in frozen soil environments. In this paper, the conductivity and lightning impulse breakdown characteristics of the frozen soil were experimentally studied, and those key factors influencing the impulse breakdown ...

Development of lightning electromagnetic impulse simulator on buildings

2010 Asia-Pacific International Symposium on Electromagnetic Compatibility, 2010
In this paper, we report the development of lightning electromagnetic impulse simulator on buildings. This simulator is linked with the counting code VSTL (Virtual Surge Test Lab.) based on the FDTD (Finite Difference Time Domain) method being developed by Central Research Institute of Electric Power Industry.

Development of the lightning measure technique and applications using lightning electromagnetic impulse simulator

2012 International Conference on Lightning Protection (ICLP), 2012
We have developed the electromagnetic impulse simulator by FDTD method (Finite Difference Time Domain Method), in order to analyze the situation of current diversion and the effects of electromagnetic field in the building by lightning strikes. Also we have experimented using the 1/4 scale model of a 3-story building. The situation of current diversion

A Review of Dielectric Strength with Distorted Lightning Impulses

2016
Non-standard and distorted lightning impulse voltages are often actual dielectric stresses on high voltage insulation, either in laboratory tests or in service. The standard lightning impulse 1,2/50 s conveniently allows comparing the results obtained in different laboratories.
